“Those who eat vegetarian food face a deficiency of Vitamin B12 and this is one of the reason behind cardiovascular diseases. On the other hand, this vitamin is available in plenty in non-vegetarian food. Vitamin B12 deficiency increases the levels of homocysteine, an amino acid.

Who consume non-vegetarian food occasionally are not protected. The risk in vegetarians is four times higher than in non-vegetarians,” the study revealed.

The study found that if the body poses a higher level of homocysteine, it increases the chances of blood clotting, which squeezes the blood vessels. Thus it decreases the flow of blood supply to the brain and causes stroke.

“This is known as ischemic stroke. It can cause significant disability in the form of paralysis, loss of speech, loss of vision, unsteadiness, double vision or even loss of consciousness. If blood supply to a major part of brain is compromised, it can cause early death,” the study added. Those who are vegetarian should take vitamin B12 supplements
